  • Method of preparing colloidal sol of antimony oxide
    Patent number: 4110247
    Abstract: A method of preparing a colloidal aqueous dispersion of antimony pentoxide from substantially water-insoluble metal antimonate is described. The method comprises contacting an aqueous slurry of the metal antimonate with a cation exchange resin whereby the metal antimonate is converted to the colloidal antimony pentoxide. A preferred method involves passing the slurry of metal antimonate through a fluidized bed containing a cation exchange resin. The colloidal sols obtained in the prescribed manner are useful as flame retardants when combined with halogen compounds.
